Association between preoperative respiratory symptoms and perioperative respiratory adverse events in pediatric patients with positive viral testing.

Study Objective: To determine the association between the presence of upper respiratory tract viral infection symptoms and occurrence of perioperative respiratory adverse events (PRAE) in children with positive viral screening, and to analyze the risk of PRAE in children with SARS-CoV-2 compared to non-SARS-CoV-2 infection.

Design: A prospective cohort study.

Setting: A tertiary, freestanding pediatric hospital in Dallas, Texas.

Intraoperative fluid administration volumes during pediatric liver transplantation and postoperative outcomes: A multicenter analysis.

Introduction: Fluid administration is an important aspect of the management of children undergoing liver transplantation and may impact postoperative outcomes. Our aim was to evaluate the association between volume of intraoperative fluid administration and our primary outcome, the duration of postoperative mechanical ventilation following pediatric liver transplantation. Secondary outcomes included intensive care unit length of stay and hospital length of stay.

Management of the Normal and Difficult Pediatric Airway: Unique Challenges in the Time of COVID-19.

Purpose Of Review: This review focuses on the challenges faced by acute care healthcare workers in the management of the normal and difficult pediatric airway during the COVID-19 pandemic and how these protocols and practices evolved during the pandemic. The current state of knowledge on timing of surgery and anesthesia is also discussed.

Recent Findings: In the early days of the pandemic, information about the SARS-CoV-2 virus and disease process was scarce.

Changes in the Nociception Level Index During Surgical Resection of Paragangliomas: A Case Report.

Nociception is the detection of noxious stimulation by the nervous system. The PMD-200 monitor is a validated, emerging technology for intraoperative monitoring using the nociception level (NOL) index. We describe a pediatric case of an open resection of paraganglionic masses during which episodic increases in NOL index and blood pressure coincided with tumor manipulation, presumably due to a catecholamine surge.

Anesthetic Management of Children With Propionic Acidemia Undergoing Esophagogastroduodenoscopy.

Propionic acidemia is a rare genetic disorder of metabolism that predisposes patients to metabolic acidosis, lethargy, neurologic dysfunction, developmental delays, and cardiomyopathy. Perioperative anesthetic management is guided toward mitigating the effects of preoperative fasting times, maintaining normovolemia, and preventing cardiovascular complications secondary to underlying cardiomyopathy. Commonly used anesthetic agents may have undesirable side effects in these patients.

Anesthetic Complications Associated With Severe Acute Respiratory Syndrome Coronavirus 2 in Pediatric Patients.

Background: Coronavirus disease 2019 (COVID-19) is associated with high perioperative morbidity and mortality among adults. The incidence and severity of anesthetic complications in children with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is unknown. We hypothesized that there would be an increased incidence of intra- and postoperative complications in children with SARS-CoV-2 infection as compared to those with negative testing.

Endotracheal Intubation Using Alfentanil in a Pediatric Patient with a Mitochondrial Myopathy and Gastroparesis.

Children with mitochondrial disorders represent a subset of patients who require unique anesthetic considerations. Routinely administered medications for general anesthesia, such as propofol, have been shown to increase the risk of developing metabolic acidosis. In addition, both depolarizing and nondepolarizing neuromuscular blockers are contraindicated due to the risk of hyperkalemic cardiac arrest and worsening of preexisting muscle weakness, respectively.

Aortopexy Complicated by ST Segment Elevations in a Four-Month-Old Infant.

A four-month-old female infant presented for a thoracoscopic aortopexy for severe tracheomalacia. The case proceeded uneventfully until a specimen bag was introduced into the chest to remove the thymus. The child developed significant ST segment elevations in all 12 leads on electrocardiogram.

Use of dexmedetomidine and opioids as the primary anesthetic in infants and young children: A retrospective cohort study.

Background: Anesthetic regimens using dexmedetomidine and short-acting opioids have been suggested as potential alternatives to sevoflurane-based anesthesia in children. The primary aim of this study is to compare demographics, intraoperative characteristics, and complications of general anesthetics in which dexmedetomidine and opioids were used without sevoflurane, or in combination with a low sevoflurane concentration, in children 36 months old and younger. The secondary aim is to evaluate intraoperative bispectral index (BIS) values when available in these patients.

An open label pilot study of a dexmedetomidine-remifentanil-caudal anesthetic for infant lower abdominal/lower extremity surgery: The T REX pilot study.

Background: Concern over potential neurotoxicity of anesthetics has led to growing interest in prospective clinical trials using potentially less toxic anesthetic regimens, especially for prolonged anesthesia in infants. Preclinical studies suggest that dexmedetomidine may have a reduced neurotoxic profile compared to other conventional anesthetic regimens; however, coadministration with either anesthetic drugs (eg, remifentanil) and/or regional blockade is required to achieve adequate anesthesia for surgery. The feasibility of this pharmacological approach is unknown.
